¦ All Pollutants: Sampling ended mid-2018
o 171 of 252 pollutant datasets were suitable for trends analysis
o Annual Average and 3-Year Rolling Average Concentrations were generally flat over time,
o 100% Reporting of Datasets
• Method Quality Objectives (MQO): 2003-2018
o Completeness: Met 85% completeness in 179 of 254 pollutant datasets
o Method Detection Limits: Met MDL Target Ratio of 1.00 in 216 of 271 pollutant datasets
o Bias: Met ±25% for 159 of 178 pollutant datasets
o Overall Method Precision: Met <15% CV for 26 of 106 pollutant datasets
o Analytical Method Precision: Met <15% CV for 88 of 178 pollutant datasets

National Summary: NATTS data were collected at 27 locations across the United States,
with sites beginning in 2003 or later (Figure 1) for 19 core HAPs. Over 528,000 concentrations
(primary, secondary, and replicate) were generated and analyzed for this assessment. Pollutant
datasets were scored to assess whether they were suitable for trends analysis. Each
pollutant dataset was evaluated against four MQOs: Completeness; Sensitivity; Bias; and
Precision. Datasets that were suitable (A- or B-rated) for six consecutive years were used for
national trends analysis (Table 1).
National trends were determined by comparing the most recent 3-year blocked averages
(e.g., 2013-2015 vs. 2016-2018) to determine if the NATTS Trends DQO was being met:
To be able to detect a al5percent difference (trend) between the annual mean
concentrations of successive 3-year periods within acceptable levels of decision error.
Of the 19 core HAPs. 18 were assessed for the NATTS Trends DQO. Due to sampling and
analytical issues, acrolein was not considered for trends analysis (Table 2). This assessment
showed that across the network, 15 of those 18 pollutants were decreasing between the
3-year blocks, while two of those pollutants were increasing between the 3-year blocks.
One pollutant did not exhibit a trend.

A-rated:< 15% CV
B-rated: Between 15%CV to25% CV
Does Not Meet: >25% CV or did not report Precision (required in the NATTS Workplan Template since 2012)
No data available
a: Per the NATTS Workplan template, analytical replicates were required to be reported to AQS for this sampling year
b: The primary and/or replicate value were less than the MDL, so no calculation could be made.
